Title: Improvements in and relating to games apparatus
IPC: A63F7/26
Filed: 1939-09-16
Abstract: 534,836. Coin-freed game apparatus. BURT, F. A. Sept. 16, 1939, No. 25971. [Class 132 (ii)] [Also in Group XVIII] In a table game apparatus wherein the balls are raised from a magazine to the ball-propelling plunger by an electrically-operated transfer device such as a solenoid, the transfer device is brought into operation for the first ball in the magazine by control means operated by the last ball in the magazine, and for subsequent balls by control means adapted to function as a preceding ball passes out of play. As shown, the balls after projection up a side channel 19, Fig. 2, run down the playing area and pass out of play into an " out-of-play " compartment 2 where they remain until released by manual actuation of the coin slide 3 when they run into the retaining runway or magazine 10, Figs. 2 and 3. The first ball 15 closes a switch 8, Figs. land 3, and the last ball closes a switch 9 whilst a switch 12 remains closed until a ball is elevated. A circuit is thus completed through the solenoid and the first ball is raised by the movement of the core 17 and occupies a position (shown by broken lines in Fig. 3) in front of the usual projecting plunger, at the same time opening the switch 12 and de-energizing the solenoid. As the switch 9 is opened during this elevating movement, a holding switch 7 is provided to maintain the solenoid circuit until the elevation of the ball is completed. After projection of the raised ball, it eventually passes over a switch 11, Fig. 2, and the solenoid is again energized and raises a urther ball, the action being repeated each time a ball passes over the switch 11 until the balls in the runway 10 are exhausted. An emergency switch 14 operable by a key is provided for use if a ball should fail to be raised. A multiple stage solenoid as shown may be used when a large core movement is required.

Title: Improvements relating to sliver balling machines
IPC: D01G27/04
Filed: 1932-09-20
Abstract: 404,764. Sliver balling apparatus. FRASER, G., FRASER, N., and FRASER, J., Westburn Foundry, Arbroath, Angus. Sept. 20, 1932, No. 26108. [Class 120 (i).] In a sliver-balling machine of the type in which the balls or rolls are wound by frictional contact with a rotating driving roller, measuring gear is provided including a ratchet-wheel 8 which performs one revolution while a predetermined length of sliver is being wound, a striker 10 rotating therewith and being adapted to trip a latch 11 to bring about operation of the roll-ejecting mechanism. In a machine of the type described in Specification 323,416 the gear comprises an eccentric 1 which is rotated from the driving shaft 2 through a gear train including a change wheel 3, and which actuates a rod 6 connected to the pawl 7 of the ratchetwheel 8. On completion of the roll the pin 10 engages the arm 35 of the lever 34, 35 carrying the latch 11 and trips the latter out of engagement with a stud 12 fixed to a lever 13 pivoted at 14 which is then allowed to swing forwardly. A stud 16 on the lower end of the trigger arm 17 is freely slidable in a slot 15 in the lower end of the lever 13, a face 18 on the arm 17 being engageable with an inclined face 19 on an adjustable trigger pin 20. The pin 20 is adjusted so that the arm 17 is free to move forwardly shortly before the roll is completed, the stud 1 however preventing any forward movement of the arm 17 until the latch 11 is disengaged. A chain wheel 21 fixed to the ratchet-wheel 8 drives a second chain wheel 23 unitary with a hand-wheel 24 having a mark 25 which at commencement of winding is set opposite a fixed pointer 26, the ratchet-wheel 8 being thus turned until the pin 10 is in the position it occupies at the completion of the roll. The lowering cam 27 on the shaft 2 now engages an adjustable pin 28 on the arm 17 which is pushed backwardly until the face 18 rides down the incline 19, the stud 16 simultaneously pushing the lever 13 back until the latch 11 drops into engagement with the stud 12. As the roll is built the arm 17 rises and the ratchetwheel is slowly rotated by the pawl 7 until the pin 10 disengages the latch 11 from the stud 12 and allows the members 13, 17 to swing forward and eject the roll.

Abstract: 624,184. Electric spark igniters; open tray oil burner. GENERAL BRONZE CORPORATION. Aug. 30,1946, No. 26118. Convention date, Jan. 29. [Class 75(i) and 75(iii) [Also in Group XXVII] An igniter for a vaporizing bowl type of oil burner comprises a pair of spaced electrodes having relatively long spark portions arranged side by side and means disposed between, and substantially throughout the lengths of, the electrodes for carrying and holding in a dispersed state a quantity of oil which will be exposed to the ignition spark. A pair of electrodes 13, 14 extend downwards from an insulator 12 removably mounted in an opening in the burner casing and terminate just above the bottom of a vaporizing bowl 5. A porous heat resistant material (firebrick) 18 of low specific heat is supported between the electrodes by a cage comprising the two electrodes and two elements which are connected to the lower end of one of the electrodes 13 and are co-extensive with the electrodes. The firebrick 18 raises oil by capillary action from the bottom of the bowl and presents it in a dispersed state to the electrodes where it is vaporized and ignited by the ignition spark. Irrespective of the oil level in the bowl the firebrick will always carry a relatively small quantity of dispersed oil which on ignition will quickly raise the entire body of oil in the bowl to combustion temperature. The burner bowl is secured in a burner casing having an inner and outer shell and oil is supplied to the bowl through an orifice 11 located above the bottom of the bowl. A room thermostat in a low tension electric circuit controls an electric switch in the primary circuit of a step-up transformer connected to the electrodes.

Title: Purification of argon
Inventor: ARMOND JOHN WALTER
IPC: C01B23/00
Filed: 1956-08-29
Abstract: Methane and/or nitrogen, constituting impurities up to 0.5 per cent of an impure argon, are removed by passing the impure A through an adsorbent bed of activated Zeolite A, or Zeolite X. Zeolite A is a sodium calcium aluminium silicate, prepared as, and having the structure, described in Specification 777,232, of composition 1.0\sB0.2M 2/n O : Al2O3 : 1.85\sB 0.5 SiO2.YH2O, where M is part Na and part Ca, which is 40 per cent or more of the total metals, n is the valency of M, and Y is a number not above 6.  Zeolite X is a sodium aluminium silicate, prepared as, and having the structure, described in Specification 777,233, of composition 0.9\sB0.2 Na2O : Al2O3 : 2.5\sB0.5 SiO2 YH2O, where Y is a number not above 8.  The zeolite is activated by heating under vacuum, <PICT:0809168/III/1> or in a dry purge gas, which is not absorbed.  The impure A is preferably passed through at a space velocity not exceeding 1000 v/v/hr.  Impure A at slightly above atmospheric pressure from 11 passes through heat exchanger A, where it is cooled to 90 DEG  K. The cooled A passes through 10 and valve V1 into zeolite in vessel B, which is cooled, to maintain a temperature of 90 DEG  K, by liquid O2 passing through V9 and coil D.  Vaporized O2 passes out through V15 and pipe 15 and heat exchanger A in countercurrent to the incoming A. Pure A leaves vessel B through V3, pipe 12, and heat exchanger A in counter-current to the incoming A.  The zeolite in vessel C is meanwhile regenerated by draining residual liquid O2 from coil E through V14 to 14, while air or N2 is passed through V12, coil E, and V18.  Electric heating coil N raises vessel C to ambient temperature, when flow of air or N2 through coil E is cut off, and vessel C is evacuated to 1 mm. Hg. pressure by opening V8.  When the selected regeneration temperature, e.g. 100 DEG  C. is reached, heater N is switched off, and cooling air or N2 is again passed through coil E by opening V12 and V18.  As vessel C cools, impure A is admitted by opening V2 and V6, and liquid O2 is passed through coil E by opening V10 and V16.  The vessels B and C are then changed over, and impure A is passed through vessel C, while vessel B is regenerated.  The necessary change-over of B and C is determined by analysis of the pure A stream.

Abstract: 1,168,118. Automatic control of current and voltage. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. May 16, 1968 [June 13, 1967], No.27142/67. Heading G3. A power supply regulating circuit includes first means for sensing the magnitude of the output of the circuit to operate current limiting means in the event of a limit current tending to be exceeded and second means, responsive to the proving of the first means by the sensing of at least a nominal current thereby, to with-hold an otherwise over-riding limitation upon the operation of the circuit. As shown, a load 7 is supplied from a D.C. source 19, 20 by way of a rectifier bridge, including thyristors 15 and 16, and a smoothing circuit 21, 22; firing signals derivedfrom a drive circuit 25 control the thyristors 15, 16 to maintain the load voltage constant, this voltage control being superseded by current control when the load current reaches a predetermined value. The drive circuit is actuated to effect the desired regulation by a control signal derived from a comparator 30 which receives a voltage-dependent signal from a voltage divider 23, 24 connected across the load 7 and a currentdependent signal from a current sensor 6, associated with a rectifier 9, connected in the input circuit of the rectifier bridge 15-18. The parallel combination of a transistor 4 and a resistor 31 is included in the control signal path between the comparator 30 and the drive circuit 25, and the transistor is rendered conductive by way of a circuit including a capacitor 10 and resistors 27, 28, 29 when a current is detected by the sensor 6 to provide a low-impedance path for the control signal; should the current sensor 6 or associated circuitry fail, however, then transistor 4 assumes its non-conductive state and the resistor 31 is inserted into the control path so that only an attenuated signal reaches the drive circuit 25 and the output current is automatically limited to a safe value.
